The Lee-Speedrifle was a bolt action rifle based on James Paris Lee's rear-locking bolt system and detachable magazine. Early models were fitted with barrels using the radiused rifling designed by William Ellis Metford.[1][2] while later models used the same square "Enfield" rifling as contemporary British military rifles.

The weapon was a sporting variant of the well known Lee–Metford and Lee–Enfield rifles made for civilian shooters, though often purchased by Army officers who wanted a rifle made to a higher standard of fit and finish than the issued military rifle.
